Any hints or tips to trim the addresses? I've already gone through and deleted some just by skimming. We've got a big job ahead of us and any tips would be appreciated.
When you skimmed through the addresses, did you remove them one-by-one? If so, there is an easier way.
Open up OE, then open your address book.
Hold down the ctrl key, click on the address to be deleted.
Keep holding down ctrl, keep clicking on the addresses.
After you have some highlighted, RIGHT click, choose delete, confirm that you want to delete them.
I don't know of any way to do a mass delete other than what I've told you. Someone else may be able to tell you how to speed the process along.
In the future, instead of automatically saving addresses to your address book, you can instead do this:
Open up the received message, click on TOOLS in the message.
Choose Add to Address book, then pick Sender.
